Currently, there’s a $1.6 billion allocation for the bonds, which provide cheaper financing than is otherwise available.

But with more projects than bonds right now, there’s a push to increase the amount to $3 billion.

Half the residential bonding is made through the city’s Housing Development Corp. and half through the state’s Housing Finance Agency.

Steve Hunt, president of the HFA, told The Post there are more rental projects waiting than he has authority to bond. One project may drop out, however, thus leaving enough for the last one in line.

HFA would create about 2,200 units, with over 100 affordable.

The HDC, meanwhile, approved $377.6 million for 1,048 units in three projects. But it has 10 projects to create 3,916 apartments with another $1.2 billion in bonds, said Tracy Paurowski of the HDC.

That leaves about six projects in limbo.

All are buildings with 145 to 583 apartments each that would be newly constructed or redeveloped from office buildings below Canal Street.

Downtown advocates are split over a congressional proposal to extend the Liberty Bond program another five years and increase the residential allocation, but reduce the commercial sector’s $6.4 billion portion of the $8 billion total.

Aside from 7 World Trade Center, the commercial bonding has been used in Midtown and in the outer boroughs.
